More than three, I still can't reach it.
Please help. There are ten so far and they have invited their gross friends to our home. They are using the broken lightbulb to smoke crack off of.
Only one but it takes eight million years.
How many pessimists does it take to change a light bulb? None - it's probably screwed it too tight anyhow!
